BROOM-HOLDER.

Specification of Letters Patent.

Patented Aug. 24, 1920.

Application filed April 9, 1919. Serial No. 288,834.

To all whom it may concern:

Be it known that I, HARRY D. NEFF, a citizen of the United States, residing at Cambridge, county of Middlesex, Commonwealth of Massachusetts, have invented certain new and useful Improvements in Broom-Holders, of which the following is a specification.

This invention relates to a holder for a broom or brush of the refill or replacement type, and has for its object to provide a simple and inexpensive holder for the broom fibers, which while positively clamping the fibers in position, will permit the substitution of a new fill when desired.

As illustrative of my invention I have shown and described a holder for a broom composed of a plurality of removable and replaceable brush units, although it will be understood that my holder may be used in connection with various styles and types of brushes. Throughout the specification and drawings like reference characters are correspondingly applied, and in the drawings:

Figure 1 is a front elevation of a holder in accordance with my invention.

Fig. 2 a central longitudinal section thereof.

Fig. 3 is a detail view of the sliding spring clamping plate of the holder, removed.

Fig. 4 is a vertical section on the line 47- 1 of Fig. 1, and

Fig. 5 is an elevation, partly broken away, of a modification.

My holder consists of a downwardly flaring hollow one-piece member 1 comprising spaced front and rear walls open at their lower ends and closed at their upper ends, and connected to each other at their lateral edges. The upper wall of the holder 1 provides a flat internal seat 2 for one or more brush sections or units S, S and is formed with a socket 3 for a handle H. The front wall of the holder is cut-out, as indicated at 1 to receive a removable spring clamping plate 4., which is provided with guide lugs 5 and a locking lug 6 adapted for engagement under the edges of the holder adjacent the cut-out, the lug 6 having a hole 6 adapted to look into a location point 6 formed in ph holder adjapent the upper edge of the cut-'ofiTTlieplate compresses the underlying brush sections S against the opposed rear wall of the holder.

Immediately below the seat 2, the front and rear walls of the holder extend downwardly in substantially equally spaced relation providing a buttreceivin compartment for the brush sections S, into which the butt ends of said sections are inserted from below to seat flatly against the seat 2. Below the upper edge of the cut-out, the front and rear walls of the holder taper downwardly and inwardly toward each other, while widening in a lateral direction, providing a chamber in which the brush sections S are positively clamped against endwise movement but have capacity for lateral expansion or spread. The walls approach their point of greatest constriction along the indicated line 7 below which they extend downwardly in substantially equally spaced relation as a clamping throat 8.

As here shown, the holder accommodates four removable and replaceable brush sections or fills S, S The two end sections S are positively clamped between the front and rear walls of the holder proper, and the two intermediate sections S which underlie the cut-out 1 are clamped against the rear wall of the holder by the spring clamping plate 4. Said plate is bent or sprung inwardly along the indicated line 4 providing a clamping edge adapted to be coincided with the clamping edge 7 of the front wall of the holder and cooperating therewith to removably clamp the brush fills S in place in the same manner that the fills S are clamped by the holder proper.

In filling the holder shown in Figs. 1 to 4, the end brush sections S are first inserted in the holder with their butt ends seating flatly against the wall 2 at the upper end of the holder, and are clamped between the opposed clamping edges 7 of the holder. The intermediate brush sections S are then introduced within the holder and clamped by means of the plate 4: which is applied by inserting the bottom set of lugs 5 under the vertical edges of the cut-out 1 and sliding the plate upwardly until its upper set of lugs 5 and the locking lug 6 pass under the horizontal edge of the cut-out, pressure being placed on the upper half of the plate to spring the plate sufficiently to permit said lugs to seat under the adjacent edges of the holder, thus putting the plate at under tension to tightly clamp the underlying brush sections S against the opposite rear wall of the holder. Y

The clamping edge 7 of the side wall 7, cooperates with the clamping edge l of the plate l to yieldingly hold the brush sections 8 in position in the casing, being assisted in such action by the resilient character of the' 'material comprising the brush sections.

The resiliency of the brush sections aids also in retaining the plate 4 in the closed or looking position, while allowing said plate to be readily removed'from the casing should it be desired to renew the brush sections. Such construction enables me to dispense with the screws, bolts and nuts,'etc., which in'prior constructions have been deemed to be indispensable. I V In the modification shown in Fig. 5, the upper end of the holder 1 is rounded as indicated at 10, and the seat 2 for the brush sections may be a flat strip 11 attached as at 12 to the handle internally of the holder. In this figure, also, I have indicated at 9 a pivoted presser bar underlying the plate 4 and cooperative therewith to compress the brush sections S By removing the plate and swinging the presser bar on its pivot, the cut-out 1' is uncovered to permit insei tion and removal of the intermediate brush sections S 7 r Various modifications in the formand construction of my device may obviously be made, within the limits of the appended claims.

What I therefore claim and desire ,to secure by Letters Patent is V l. A- brush holder consisting of a hollow casing downwardly and outwardly flared and shaped at its upper end to provide a flat internal seat for a plurality of bundles of brush fibers inserted into said holder from below and having a cut-out in one vertical wall below said seat of the width of at least one bundle of brush fibers, said casing between the upper edge of said cut-out and the said seat constituting a butt receiving compartment of substantially uniform' width, and below said upper edge of the cut-out tapering inwardly and widening laterally to provide opposed clamping edges adapted to clamp the inserted brush bundles against endwisemovement while permitting limited lateral expansion thereof, and a removable spring closure for said cut-out shaped to conform to the casing at said cut-out and clamping the underlying brush bundle against the opposed wall of the head.

- 2. A holder for a plurality of compressible brush units adapted to be removably and replaceably confined therein, comprising a casing open at its lower end and having a brush'receiving compartment and a filling opening through which the brush units may be inserted into said compartment, said casing below said compartment providing a brush clamping portion against which the brush units may expand, and a removable closure for said filling opening adapted to slidably engage said casing and to be put under tension, thereby tofrictionally clamp an underlying brush unit.

- In testimony .whereof'l afiix my signature in" presence of two witnesses.
